Abstract
An apparatus includes a recreational vehicle genset having an engine and a generator. The apparatus includes a fuel injection system having a primary fuel reservoir, a secondary fuel reservoir, and a fill pump that receives fuel from a primary fuel reservoir and is fluidly coupled to the secondary fuel reservoir at the pump outlet. The apparatus includes a reservoir fuel indicator that provides a fuel amount signal corresponding to the fuel in the secondary fuel reservoir, and a pressure regulator that relieves pressure in the secondary fuel reservoir at a threshold relief pressure. The apparatus includes an injection pump that provides pressurized fuel from the secondary fuel reservoir to a fuel injector for the engine. The apparatus further includes a controller having a pump regulation module that interprets the fuel amount signal, and that selectively provides a fill pump operation command in response to the fuel amount signal.
